Partition or subdivision
A partition creates parcels. A subdivision creates lots. The words are not decorative — they select which body of law and which county process you are subject to, and partitions are meaningfully less burdensome.
The line is drawn by counting the units produced by one or more divisions of the same tract in a single calendar year: three or fewer are parcels, four or more are lots.
Zoning is the harder gate
Chapter 92 tells you the procedure. Your zone tells you whether there is anything to procedure about. EFU and forest zones carry minimum parcel sizes that are large by design, and the entire point of resource zoning is to stop working ground being chipped into homesites.
So the sequence is: find out your zone and its minimum parcel size first. If the split you have in mind would create a parcel under that minimum, the partition process is not the obstacle — the zone is, and no amount of surveying gets around it.
What the county will want to see
Legal access to each new parcel. A parcel with no enforceable access to a public road is a problem you are creating for yourself and for whoever buys it.
Septic feasibility for any parcel intended to be built on — which means a site evaluation, which means test pits.
Water. Whether each parcel can actually be served, and on what.
A survey and a recorded partition plat. This is a real project with real cost and a real timeline, not a paperwork afternoon.
The consequences people miss
Special assessment. If the ground is in farm or forest deferral, understand what the split and the resulting use do to that status before you start. Recording a subdivision plat is itself a disqualifying event for farm use special assessment.
Dwelling rights. Splitting can change what is approvable on what is left. Where a lot of record dwelling is allowed, the remainder of the tract gets consolidated — you do not get a house and keep the pieces separately saleable.
The value question. Two parcels are not automatically worth more than one. Sometimes they are worth less, because the thing that made the property desirable was that it was whole.
Start here
Call Lane County Land Management with your tax lot number and ask two questions: what is the minimum parcel size in this zone, and is a partition of this tract approvable at all. Free, and it saves surveyor money on parcels where the answer was always no.
If the answer is yes, the next calls are a surveyor and a land use planner. If the ground is in deferral, add your CPA before anything is recorded.
